Configuring calendar sets
(Not available for i-on Compact.)
You can use
System Config
– Calendar Set
to configure the control unit to
set or unset the alarm system (or parts of it) at fixed times of day on a
seven-day cycle. If the system is a part-setting system, you can use this
option to full set or part set B, C or D. If the system is a partitioned system,
this option allows you to full set or part set any collection of partitions.
There are two basic elements that you can program within the calendar set
option: the “event” and the “exception”. An event defines an action (setting,
part setting or unsetting) to occur regularly at set times and days. An
exception defines periods such as holidays when you do not want the event
to occur. The number of events and exceptions the control unit can store is
dependent on the control unit model.
Hint: Set up exceptions first, and then the events.
Note:
You should not program an event to change the system/partition
directly from one part set level to another. You should program an
event to unset the system/partition first, and another event to set the
system/partition to a different part set level. For example, if event 01
part sets the system (or a partition), do not program event 02 to full set
the system. Instead, program event 02 to unset the system and then
use event 03 to full set the system.
If you create an event to unset a partition, and another event to set the
same partition again, you must program the setting event to occur at
least 10 minutes after the unsetting event.
The control unit adjusts its clock in Spring and Autumn to allow for
Summer Daylight Saving Time. At the Autumn change-over, avoid
configuring any unset events to take place during the changeover time
on the Sunday morning. For UK systems, this time is 01:00 to 02:00.
For EU control units, this time is 02:00 to 03:00. If the control unit
unsets any part of the system at these times, it will NOT set the
system again when the clock changes back to Winter Time.
Manually setting and unsetting partitions does not alter the times
programmed in calendar sets. If a user sets a partition that is due to be set
by a calendar event, the partition remains set when the calendar event time
is past. Likewise, if a user unsets a partition before a calendar event is due
to unset the partition, the partition remains unset.
